Application filed September 4, 1919. Serial No 321,697.

To all to 7mm it may concern Be it known that I, AUoUsTo Near PLA: TERO,citizen of the Republic of Uruguay, residing at No. 1568 Calls Solis,Montevideo, Uruguay, have invented certain new and useful Improvementsin Collapsible Holders for Sharp-Edged Blades or Instruments, of whichthe following is a specification. A

The present invention relates to improvements in collapsible holders forsharp edged blades or instruments its end being that of providing acollapsible holder for sharp edged blades or instruments which, due toits construction, allows the replacement or change of said blades orinstruments in a quick and safe manner, permitting its handle andpressing piece to take the place of a box or cover once the holder isshut.

In order that my invention may be clearly understood, I represent it inthe accompany ing; drawings in which- Figure I is a front view of myholder with its parts opened and showing the arrangements in detail.

Fig. II is a front view of the same holder shut.

Figs. III, IV and V are end views taken from one of the extremities ofthe holder.

In Fig. I, e and e are two sheets made of metal or any other suitablematerial as are all the other parts of my holder which carry the sharpedged blades or instruments. The sheet 6 is not shown in detail in theaccompanying drawings as same goes placed behind sheet 0. Sheets 8 and eare of identical shape and size. The sheet 6 carries in its internalface some knobs (Z which fit exactly in some holes 0 of sheet 6, asshown in the drawings. The sharp blades or instruments which are usedwith my holder and are placed betweenthe two sheets 6 and e carry inidentical position and distance, holes exactly as those 0 of sheet 6, sothat when the blades or instruments are placed between said two sheets aand e, the holes correspond exactly and allow the passage of knobs (Z ofsheet a. In this way sheets 0 and e and the sharp edged blade orinstrument are made secure preventing any vertical movement. Theposition of sheets 6 and e are more clearly represented in Fig. IIIwhich shows said sheets in end view, separated, without carrying thesharp edged blade or instrument in between.

Near one of the extremities of sheets e and e is securedby means of apin, screwor r vet, but with free movement, a U-shaped piece f whichstraddles the upper part of the sheets 6 and e as shown in the drawings.This U-shaped piece f on being straddled over the two sheets 6 and e, asshown in Fig. II, presses said sheets and the biade or instrument inbetween so that the combination forms a solid whole which prevents anymovement of the blade or instrument and besides, said U-shaped piece 7serves as the lid of the box or cover of the collapsible holder. In thesame section of the sheets 0 and 6 but nearer the extremity, there isalso secured by means of a pin, screw or rivet, with free movement,another U-shaped piece 9 which serves as a handle as well as the lowerpart of the box or cover of my holder when same is shut, as it appearsin Fig. I (partly opened) and in Fig. II (shut).

Fig. II shows my holder shut, with piece 7 straddled over the sheets aand e which carry the sharp edged blade or instrument, and thehandle-piece g shut.

Fig. III is an end view of the sheets e and e separated, showing theposition of the holes 0 and knobs d.

' Figs. IV andV show the same sheets 6 and e pressed by the. U-shapedpieces f and g.

The manner in which my collapsible holder of sharp edged blades orinstruments is set up, is as follows: The different pieces of my holderbeing opened, the sharp edged blade or instrument to be used is placedin between sheets 0 and e, so that its holes correspond to those ofsheet 6, inserting in same the knobs d of sheet e; this done U-;

shaped piece f is straddled over said sheets 0 and e and blade therein,thusforming a solid whole which prevents any movement to its parts. Thehandle-piece g is then opened to its limit, which is a horizontal linewith sheets 6 and e and my holder is ready for use. When it has beenusedthe handle-piece g is shut until it straddles the lower part ofsheets 6 and c and the blade or instru ment therein thus forming thelower cover of the box of the holder;

Having thus described the nature of my invention and the manner in whichsame is to be carried into practice, what I claim as my exclusiveproperty and use is:

1. A device for holding and protecting a double-edged bladev comprisingparallel metal base plates secured together at one end only, one of saidplates being provided with a plurality of apertures, a plurality of pinsprovided on'the other section designed to engage a blade and adapted toenter said apertures, a first cover plate of U-shaped crossesectionhaving parallel side portions pivotally connected to the base plates,de-

i signed to engage said base plates torholding the same together, andadapted to protect one edge of a blade .heldby the base plates and asecond cover plate pivotally connected to the base plates and movable,into alinement With said base plates to form a handle, the second coverplate being also movable'into substantially parallelrelation to the baseplates for protecting the other edge of the blade. 7

2. A device for holding and protecting a double-edged blade comprising aclamp adapted to hold a double-edged blade, a first cover memberpivotally connected to said clamp, holding the same in locked positionand adapted to protect one edge of a blade carried by said clamp and asecond cover member pivotally connected, to the clamp and movable intopositions in alinement With and parallel to said clamps for forming ahandle for the clamps and a protector for the other edge of the blade. r

In testimony whereof I affix my signature in presence of two Witnesses.AUGUSTO near PLATERO.
